SPECIFICATION forming part of Letters Patent No. 393,720, dated November27, 1888.

Application filed September 15, 1888. Serial No. 285,516. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH SMITH Poona, a citizen of the United States,residing at His ing Sun, in the county of Cecil and State of Maryland,have invented new and useful Improvements in Thill-Gouplings, of whichthe following is a specification.

The invention relates to improvements in thill-couplings, the objectsbeing to prevent the parts from rattling and to provide means for takingup the wear of the thill-iron and the bearings thereof; and it consistsin the constructionand novel combination of parts,hereinafter described,illustrated in the drawings,

0 and pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a thill-couplingembodying the invention. Fig. 2 is a top or plan view of the heel of thethill and the thill-iron detached from the clip. Fig. 3 is a horizontalsection on the line a x of Fig. 1. Fig. 4; is a side view of theadjusting-bolt and its nut detached from the clip. Fig. 5 is a detailview of the clip-plate.

Referring to the drawings by letter, A designates the front axle of avehicle, having attached the clip B, the lower bar or plate, 0, of whichis provided with the central transverse bolt-opening, c, and has in itsrear end the transverse notch 0, preferably rectangular incross-section. The front end of said clipbar is extended forward,rounded, and provided in its inner face with the conical bearing-recessD.

E is a short bar lying against the inner surface of the clip-bar,provided with abolt-opening, 6, that registers with the opening 0, andhaving a projection, e, that fits into the notch The front end of thebar E is also extended forward, rounded, and provided with a conicalbearing-recess, F, that faces and registers with the bearing-recess D.

G- is the thill-iron, secured to the thill by bolts or otherwise,andprovided atits heel with the conical journals g 9, that fit and turn inthe bearing-recesses D F.

The clip-bar O is secured to the strap thereof by nuts on the threadedends of the said strap in the usual manner. H is a bolt that passes intothe openings 0 and e, and is engaged by an adj usting-nut, I, on itsthreaded end,which nut may rest either against the clip-bar or the barE, according to the direction in which the bolt is passed into theopenings. The said not has an extended head provided with thelongitudinal slot i, through which a strap, J, is passed and securedaround the axle by a buckle, 9.

As the journals of the thill-iron or the bearings thereof wear, the saidwear can be taken up and all jar and rattle prevented by screwing up thenut I, which is prevented from accidentally turning by the strap J.

The bar E is, by means of the adjusting bolt and nut, drawn alwayssufficiently close to the clip-bar to cause the bearing-recesses to bindclose enough on the. journals of the clip-iron to prevent rattling.

The bar E is prevented from moving longitudinally on the clip-bar by theprojection c, fitting into the notch c of the clip-bar.

Having described my invention, I claim- 1. In a thill-coupling, thecombination,with the clip having the clip-bar provided with a centralbolt-opening and the rectarigular transverse notch c in its rear end,and having its front end extended and provided with a bearing-recess inthe inner face thereof, and the bar E, provided with a similarregistering e, at its rear end fitting into the notch 0, and abearing-recess in the innerface of its front end similar to and facingthe bearing-recess in the clip-bar, of the thill-iron having oppositejournals at its heel engaging said recesses, the bolt passing throughthe bolt-opening in said bars, and the adj usting-nut engaging saidbolt, substantially as specified.
